Dirt will be flying and the engines will roar this weekend as Knoxville Raceway drivers begin preparation for the new season. The official Practice Night for the Raceway is scheduled for Saturday evening. General Manger Brian Stickel says it’s a good chance for drivers to get those first laps of the year down ahead of next week’s opening night. Practice Night is free and open to the public; cars will start turning laps at about 7pm.
